Hi,
We rescued a 3-4 year old Springer spaniel Oct this year..then she came into season, cue lead walks for 4.5 weeks. Now been off lead for 8-9 weeks. In the house she is submissive, not allowed on furniture, crate trained, eats after us, not allowed up stairs etc, only greets people when invited, never jumps. Perfect!!
Up until now she has been good in park, on lead she shows little interest in other dogs but can say hello nicely, until last Thursday was the same off lead...into hedges, chasing birds etc. not particularly wanting to play with other dogs. Thurs she stopped to say hello to large lab, it became aggressive (apparently unusual for other dog) but I could call her off, happened again on Sunday, then again twice today.
She has at least 2 hours exercise per day, half of that is off lead pretty much flat out running/spanielling about.
Any advice (PS am single parent, lots of DC so have to walk her in busy places at least some of the time)
